Specification of Letters Patent.

Patented March 19, 1907.

Application filed December 27, 1906. Serial No. 349,647.

To aZZ whom it may concern.-

Be it known that I, JOHN WALTER FINOH, a citizen of the United States, and a resident of Elizabeth, in the county of Washington and State of Mississippi, have made certain new and useful Improvements in Hand-Cars,

' of which the followingis a specification.

' section on the line My invention is an lmprovement in handcars, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof, Figure 1 is a longitudinal section through my improved hand-car. Fig. 2 is a section on the line a a of Fig. 1. Fig. 3 is a plan view of the hand-car.

Fig. 4 is a section on the line b b of Fig. 1, and Fig. 5 is a c of Fig. 3.

In the present embodiment of my invention the hand-car is of ordinary construction, comprising a frame 2, provided with bearings 4, in which are journaled the axles 3, provided with flanged wheels 5. The frame is provided with the ordinary pedestal 6 at the center thereof, and on the pedestal are the bearings 7, in which is journaled the rock-lever 8, provided with ordinary handles 9. One of the axles 3 is provided with a sprocket-wheel 10 of relatively small diameter, connected by a sprocket-chain 14 with a sprocket-wheel 13 of relatively large diameter, secured to a counter-shaft 11, journaled in bearings 12 on the frame, and having keyed to the inner end thereof a gear-Wheel 15.

A pair of spaced parallel arms 16 are journaled on the end of the counter-shaft, one of said arms being arranged upon each side of the gear-wheel 15, and in the free end of the arms is journaled a stub-shaft 17, having its ends reduced and screw-threaded, as at 18, and provided at its central portion be tween the arms with a squared portion'19, received in the correspondingly-shaped op ening of a gear-wheel 20, meshing with the gearwheel 15 before described. The inner end of the stub-shaft 17 is also provided with a squared portion 21, received in the correspondingly-shaped hole of the pitman 22, which is pivoted to one end of the rocklever, as at 24, and washers 25 and nuts 26 are arranged on the reduced ends of the stubshaft for securing the parts in their respective positions.

In operationwhen the rock-lever is rocked upon its bearings the parallel arms 16 are rotated about the counter-shaft 11, and since the stub-shaft is rigid with the pitman and the gear-wheel 20 is rigid with the stub-shaft the gear-wheel 15 is constrained to rotate and carries the shaft 11 therewith at a considerably higher speed than were the parallel arms secured directly to the shaft 11 and acting thereon as a crankarm, and since the sprocket-wheel 13 is of relatively greater diameter than the sprocket-wheel 10 this movement is further multiplied on the axle 3.

I claim 1. A hand-car, comprising a frame, axles journaled thereon, wheels secured to the ends of the axles, a sprocket-wheel rigid with one of the axles, a counter-shaft journaled on the frame, a sprocket-wheel secured thereto, a sprocket-chain connecting said sprocketwheels, a pair of spaced parallel arms journaled on the end of the counter-shaft, a gearwheel secured to the counter-shaft between the arms, a stub-shaft journaled in the free ends of the arms, a gear-wheel rigid with the stub-shaft between the arms and meshing with the first-named gear-wheel, said stubshaft having a squared portion outside of the arms, a pitman having a square opening to receive said squared ortion, nuts threaded on the ends of the stu -shaft for retaining the parts in position, and means connected with the pitman for operating the same.

2. A hand-car comprising a frame, axles j ournaled thereon, wheels secured to the ends of the axles, a countershaft journaled on the frame, a pair of spaced parallel arms journaled on the counter-shaft, a gear-wheel secured to the shaft between the arms, a stubshaft journaled in the free ends of the arms, a gear-wheel rigid with the stub-shaft be- I tween the arms and meshing with the firstnamed gear-wheel,a pitman rigidly secured to the stub-shaft outside of the arms, means connected with the pitman for o crating the same, and a driving connection etween the counter-shaft and one of the axles.

3. A hand-car comprising a frame, axles j ournaled thereon, wheels secured to the ends of the axles, a counter-shaft journaled on the with the stubshaft, means for operating the frame, a pair of spaced parallel arms jourpitman, and a driving connection. between IO nfilefd on thelerad of thefeounteg-shjaft, a stubthe eountensliaft and one of the axles. satjournae intie reeen so tiearms, r 1 1 a gear-Wheel keyed to the counter-shaft, a 1 Jon} F 13R lilkul' gear-Wheel secured to the stub-shaft, said Witnesses: gear-wheels being between the arms and M. B. SMITH, meshing With each other, a pitman rigid JACK STINSON.
